Title: Friction welding process
IPC: B23K20/12
Filed: 1965-03-05
Abstract: 1,093,632. Welding by pressuse. AMERICAN MACHINE & FOUNDRY CO. March 5, 1965 [March 13, 1964; March 25, 1964 (2)], No. 9433/65. Heading B3R. In friction welding workpieces of dissimilar metal one of which produces more upset than the other, a collet is placed about the workpiece producing most upset. A workpiece 17 of copper is mounted in the jaws 16 of a chuck 14 fixed on the hollow rotatable shaft 15 and a workpiece 13 of aluminium is mounted in the jaws 12 of a non-rotatable fixed chuck 11. A collet 21 of copper, brass, steel, alloy steel &c. having an annular cut-out 22 is placed about the end of the aluminium workpiece and the copper workpiece is rotated and pressed against the aluminium workpieee to weld the workpieces. Upset from the aluminium workpiece enters the cut-out in the collet where it is physically limited and the collet acting as a heat sink reduces the temperature of the aluminium adjacent the weld face. Nickel alloy and zinconium alloy workpieces may be similarly welded and when tubular workpieces are welded an inner plug with an annular cut-out is provided inside the tube having the collet on its end. The collet and plug may be formed as integral parts of the workpiece holding chucks. A workpiece of zinconium alloy is welded to a stainless steel workpiece containing 1% boron in an apparatus comprising a non- rotary chuck (45) (Fig. 5, not shown) movable by hydraulic cylinders (42, 43) towards a rotary chuck (46) on a shaft (47) rotatable by a belt (60) from a shaft (51). The shaft (51) carries a braking device (55) and is connectable at each end through clutches (54) (58) to a motor (52) and flywheel (57) respectively. The steel workpiece (49) is held in chuck (45) and the zirconium alloy workpieee (50) is held in chuck (46) and the workpiece (50) is rotated by disengaging the clutch adjacent the flywheel, engaging the other clutch and starting the motor. The zirconium alloy workpiece is then forced against the steel workpiece and the clutch is disengaged and brake applied and forging pressure applied. The zirconium alloy workpiece is surrounded by a retaining collar to limit and contain the upset. The workpieces may be inertia welded by engaging both clutches, rotating the chuck and flywheel and drawing the workpieces together.

Abstract: 375,443. Printing-machines. WAITE, F., Inglewood, and WAITE & SAVILLE, Ltd., Falcon Works, both in Otley, Yorkshire. March 31, 1931, No. 9683. [Classes 100 (i) and 100 (ii).] Engraved-plate printing.-In an engravedplate printing-machine, the engraved plate during its passage beneath wiping and inking devices moves along a path which is first horizontal and then is inclined downwardly. For this purpose, suitably-shaped guides 2 are provided for the carriage 3 carrying the engraved plate, and the reciprocating movement is obtained from a crank wheel 14a, Fig. 3, through a link 14b, levers 14c, 13, 11, and links 10. The ends of the links 10 are slidable in the ends of the-levers 11 with nuts on their ends, and springs 10b on the links are compressed during the movement of the platen towards printing position. The connection between the levers 11 and the lever 13 comprises a bifurcated link 13b, Fig. 1, pivoted to the levers 11 and having an extension which is slidable in the end of the lever 13. A cam 14g on the lever 13 engages a roller 13f on the link 13b, and is designed to give the requisite speed to the carriage 3 including a slowing down as the engraved plate passes under the wiping pad 4 and reaches the printing position. A spring 13d on the link 13b holds the parts 14g, 13f in contact. As the carriage 3 nears its lowest position; a cam 11c on the lever 11 engages a roller 15b on a lever 17 and compresses a spring 18a on a rod 18 pivoted to the lever and slidable in the end of a lever 21 carrying a roller running on a cam 19. On the return stroke, the energy stored by the spring plus the action of the cam 19 is utilized to help in moving the carriage upwards along the inclined guides. Inking-apparatus ; feeding webs.- Ink is supplied to the engraved plate from a duct-roller 6 by means of a roller 5 carried by a lever 22 oscillated from a cam 23 through the medium of a link 25 yieldably connected by a spring-and-nut connection 25a to the lever 22. A scraper blade 8 removes the surplus ink which runs into a trough 9. The wiping member 4 is pivoted near one end to a lever 27 and at its other end is resiliently connected to a link 28 pivoted to a crank 29 oscillated from a cam 32 through a connecting- rod 30 so that the contact of the member 4 with the plate commences at 4a and finishes at 4w. The wiping paper 33 passes from a roll 34 over the member 4 to a rewind roll 38 and is held taut by the engagement therewith of a pivoted weighted member 35.

Title: Treatment of sprayed deposit
Inventor: GO HIZO
IPC: C23C4/02
Filed: 1985-01-07
Abstract: PURPOSE:To form a dense deposit wherein a pore is not present practically in the outside layer of sprayed ceramic deposit by forming a sprayed deposit of TiC composite material on the sprayed ceramic deposit which is formed on the surface of a base metal and heat-treating the sprayed deposit of the TiC composite material in a prescribed temp. range. CONSTITUTION:After blast-treating the surface of a base metal consisting of e.g. 25% Cr cast steel to activate it, deposit is formed by thermally-spraying an undercoating agent consisting of e.g. 80% N-20% Cr. Then a sprayed ceramic deposit having about 500mum thickness is formed by thermally-spraying an overcoating agent consisting of e.g. Zr.Y on the sprayed deposit. Furthermore after the sprayed deposit having about 100-200Xm thickness is formed by thermally- spraying a TiC composite material such as TiC 5-50% Co on the ceramic deposit, this sprayed deposit is heat-treated at 500-800 deg.C at 2-5hr. As a result, the improvement of corrosion resistance of the base metal can be attained by preventing surely the penetration of a corrosive gas, a molten salt and a corrosion product, etc. for the surface of the base metal.
